First report of Columnea latent viroid on tomato in France
In summer 2007, diseased samples of tomato (Solanum lycopersicum cv. ‘Santa’) leaves and fruits were received for diagnosis. These samples had been collected in Western France in glasshouses where tomato plants were showing viroid-like symptoms including severe leaf yellowing or reddening, in addition to distortion and stunting. Results of laboratory tests revealed the presence of Columnea latent viroid (Pospiviroid, CLVd). This is the first record of CLVd in France. The origin of this infection is still unknown.
The situation of Columnea latent viroid in France can be described as follows: Present, detected for the first time in 2007 in tomato samples collected from glasshouse crops (Western France).
